Single phase induction motor has specific wiring requirements in connecting with GoHz single phase VFD, to enable your single phase motor running properly, please follow below instructions step by step:
Wiring instruction of removing motor capacitor
Remove capacitor of the single phase motor, connect the common terminal Z2/U2 (single phase motor has two windings) to the VFD's V phase, connect the other two windings U1/V1 & Z1 to the U & W phase of the VFD output terminals.
Power on the VFD, set P9-13=0, run the VFD and observe the current. If the current is too high, stop the VFD, set P0-15=10, P1-02=160, and run again. If the current still too high, stop the VFD and switch the motor connection of U & W phase.
Wiring instruction of keeping motor capacitor
Connect single phase motor input lines (L, N) to the VFD's (V, U).
Power on the VFD, set P9-13=0, run the VFD and observe the current. If the current is too high, stop the VFD, set P0-15=10, P1-02=160, and run again. If the current still too high, stop the VFD and switch the VFD's U phase to W phase.
